"i" s. l BY FIGZZ \a.f (w07 M United States Patent O 3,157,340 FAFEREARD HGGSHEAD Xacob Bougies Gay, Ir., and Frederic W. Ioswig, Paris, Ky., assigner-s to Gay-Beil Corporation, Faris, Ky., a corporation of Kentucky Filed .Iune 27, 1957, Ser. No. 668,393 3 Claims. (Qi. 229-557) This invention resides in a novel hogshead arrangement whereby the hogshead may be formed of paperboard or other formable material.

Hogsheads of the general type shown in the patent to H. G. Bell et al., dated June 12, 1951, Patent No. 2,556,- 789, entitled Barrel and Barrel Head Therefor are now Well known in the art. A satisfactory method for making such a hogshead is shown in another patent to H. G. Bell et al., dated June 5, 1951, Patent No. 2,555,530, entitled Method of Making Knock-Down Shipping Containers. A similar hogshead is shown in the patent to H. G. Bell, dated May 22, 1951, Patent No. 2,554,357, entitled Knock-Down Hogshead for Tobacco. Yet another hogshead of the general type to which the instant invention applies is shown in the co-pending application to H. G. Bell, tiled May 24, 1955, under Serial No. 510,610, entitled Improved Barrel and Barrel Head Therefor.

Two other pending applications should also be mentioned. Pending lapplication Serial No. 544,258, tiled November 1, 1955, by H. G. Bell et al., entitled Apparatus and Method for the Continuous Production of Hogsheads and the Like, and pending application Serial No. 88,726,

led by H. G. Bell et al. on lune 1, 1956, and entitled Improved Apparatus and System for the Continuous Production of Hogsheads and the Like, both disclose modern, Wooden hogsheads and improved apparatus and means for their manufacture.

The instant invention is directed to hogsheads of the same general type shown in the aforementioned patents and pending applications but differs in that certain novel adjustments have been made in order to form the hogsheads from paperboard rather than wood. This invention, of course, is directed to more than just the concept of making a hogshead out of paperboard. In order to accomplish this certain structures had to be deviesed and it is to these improvements that this application is directed.

In a co-pending application iiled of even date herewith and entitled Metal Hogshead there is disclosed a novel arrangement by which hogsheads of the same general type shown in the aforementioned patents and pending applications may be made of metal. In such co-pending application the basic concept is not just to use metal instead of wood but rather such co-pending application is directed to the novel features which permit such a change. rl`his co-pending application is mentioned herein since there is a relationship between the two and it will be understood that those features common to both the metal and the paperboard hogshead will be claimed in one of these two co-pending applications.

Also, although the instant invention is directed chieliy towards hogsheads made of paperboard, metal or other formable material might also be used even in the applicacation of the teachings herein set forth. In most cases, however, metal presents certain problems which are apparently now best solved by the teachings of the said copending application.

An important object of this invention is to provide a hogshead which is switchable with wooden hogsheads of the type aforementioned and which may even be disposable.

Another important object of the invention is to provide a hogshead which may be termed a One-Way hogshead especially adapted for shipping tobacco between continents.

"ice

Another object of this invention is to provide a hogshead which may be wrapped around a cask of tobacco after the hogshead in which the tobacco was first packed has been removed.

Another important object of this invention is to provide a hogshead which although made of paperboard may still be roughly handled without injury either to the hogshead or to the tobacco therewithin.

It is to be understood that although the invention is described in terms of a hogshead for containing tobacco the invention is not limited just to containers for tobacco; obviously other materials may be packaged in the container of this invention.

it is also an important object of our invention to provide a container rectangular in cross-section as distinguished from the ordinary barrel type now so much in use.

The foregoing objects and others will become apparent to those skilled in the art from the description of the invention to follow and from reference to the accompanying drawings, in which drawings like numerals are employed to designate like parts and in which:

Referring now especially to FIGURES 1 through 3 the paperboard blank from which one form of the hogshead of this invention is formed will be described. Again, although the invention is described in terms of paperboard it is possible that other materials may be used.

FIGURE 1 shows a paperboard blank generally indicated at 36 and having a plurality of score lines 31 which define what corresponds to staves 32 of a wooden hogshead such as shown and described in the aforementioned patents and pending applications. The blank 3i) is also scored along its top and bottom edges as indicated by the score lines 33 and 34. In addition the blank is cut so as to forrn the end iiap 35 and the pair of notches 36. The

score lines 33 and 34 define fold strips 37 and 3S.

In constructing a hogshead from the blank scored and cut as just described in connection with FIGURES 1 and 2, the blank is first folded along the score lines 33 so as to bring the upper and lower fold strips 37 against the fold strips 38. It will be understood that the top and bottom portions of the blank 30 are identical and that, therefore, like reference numerals have been employed to designate the corresponding score lines and fold strips. The blank 3d is then folded along the score lines 34 so as to bring the fold strip 37, in which the notch 36 is located, into ush contact with the body of the blank 30. This foid strip 37 will, therefore, lie against the ends of the staves 32 defined by the score lines 31. Perhaps this relationship of the notch 36 to the fold strips 37 and 38 in folded condition is best seen in FIGURE 4a.

Referring now to FIGURES 4 through 9 other stages in the formation of a paperboard hogshead according to the teachings of this invention will be described. After the hogshead has been brought to the condition of FIG- URE 3 it is then stitched so as to maintain the fold strips 37 and 38 adjacent the ends of the stave portions 32. This stitching has been shown as being accomplished by staples but it will be understood that other fastening devices may be used. These stapes 39 pass through the paperboard layers comprised of the fold strip 38, fold strip 37 and stave 32. It is preferred that there be at least one staple or fastening means for each end of each of the staves 32. In the arrangement shown there are three such staples at each end of these staves.

Although it is possible, as indicated in the said copending application entitled Metal Hogshead to form a paperboard blank with the hoop-and-liner an integral part thereof, as is specitically taught in said co-pending application for hogsheads formed of light gauge metal, it has in the case of paperboard been found more desirable to use a separate chime or hoop-and-liner which latter element is formed of a suitable metal. The hoop-and-liner for the top and bottom of the paperboard hogshead of this invention are identical and will be described with like reference d numerals. Such a hoop-and-liner is generally indicated at and is probably best seen in FIGURES 4, 6 and 7.

The chime or hoop-and-liner of the just mentioned figures comprises a band of metal which lies liush against the outside of the staves 32 as indicated at 41. The hoopand-liner 4d is bent at right angles to the band 4l and notched so as to provide a plurality of segments 42, one such segment lying across cach end of a stave 32 and the fold strips adjacent thereto. The band 40 is further formed so as to provide a portion 43 slanting inwardly and downwardly from each of the segments d2. The chime or hoop-and-liner 4t) is then return bent to provide a portion da directed towards the stave 32 at right angles thereto. The metal is then bent to provide the inner flange 45 which is at right angles to the portion 44 and parallel to the outer band 4I. The distance between the bands t1 and 45 is just suicient nicely to receive the upper or lower end of the paperboard hogshead body as dened by the staves 32 and fold strips 37 and 38.

As indicated in the exploded view of FIGURE 4 these hoop-'ind-liners 40 are simply placed on the upper and lower edges of the paperboard hogshead so as to bring them to the position indicated in FIGURES 5 and 7. Following this the members 4t) are then secured to the hogshead body. Preferably this is accomplished by driving a staple through each of the chime sections 45, fold strips 37 and 38, and stave 32. Two such staples 46 have been indicated for each of the segments 45 and corresponding staves 32.

After the hogshead has been formed in the manner indicated in connection with FIGURES l through 7, a pair of wires 47, one for the upper end of the hogshead and one for the lower end, is arranged so that there is such a wire within the area primarily defined by the chime sections 43 and 415: and the fold strip 38.

The hogshead of FIGURES 1 through 9 is now ready for use in one of two basic ways. In some instances it may be desirable to use the paperboard hogshead of this invention in the manner described in connection with the metal hogshead of the said co-pending application. When so used the wooden or other type hogshead in which the tobacco may have been prized is rst removed, thus leaving a cask of tobacco resting on a hogshead bottom and covered by a hogshead top. The paperboard hogshead of this invention is then wrapped around this cask and manipulated so as to bring the hogshead top and hogshead bottom into engagement with the chime sections 44, where they will be held between such section and the stable 46, after which the wires 47 may be tightened so as to attach the hogshead to such tops and bottoms. The just mentioned relationship between a hogshead top or bottom i3 and the chime section and staple is shown in FIGURE 11 and described in detail in pending application Serial No. 510,610 aforementioned.

Thus, as shown and described in greater detail in the said co-pending application entitled Metal Hogsheads, these paper board or metal hogsheads may be used to replace the hogshead in which the tobacco was actually prized. Because of the weight of these switchable hogsheads and because of economies realized in their manufacture, it is economical to use these hogsheads in shipping tobacco after it is prized even should one treat such hogshead as disposable or non-returnable. This is a unique result in the hogshead eld made possible by the teachings of these inventions.

It has been found, however, as also generally indicated in the said co-pending application, that these paperboard and/ or metal hogsheads might even be used in the prizing of tobacco and might even be capable of more than one such use. This leads us to the second manner in which the paperboard hogshead of FIGURES 1 through 9 may be utilized and this will be described as follows.

In FIGURE 10 the paperboard hogshead is being made ready to have tobacco prized therein. In order to do this there is a support 49 ion which rests a hogshead bottom 48. The paperboard hogshead is gathered around this bottom and the wires 47 tightened so that the bottom 48 is located with respect to the chime portion 44 and staple 46 in the manner shown -in FIGURE 11. T he hogshead in then removed from the support and turned right side up so as to put the lid member 4S on the bottom. FIGURE 12 shows the bottom head i8 in place.

There are several ways in which the paperboard hogshead of FIGURES through 12 may be prized with tobacco. In FIGURE 13 there is shown a rig comprised of a shell Sii supported on vertical legs 5 1 and having clamps 52 for engaging the upper part of a hogshead 3). The hogshead 30 rests on a support 53. With the hogshead properly fastened to the charger shell 50 a prizing machine 55 then operates to introduce tobacco within the hogshead 3@ (vis the shell Si?) and periodically presses same therewithin'. Since the weight of the shell 50 is supported from the legs 51 and since the basic pressures occurring during the prizing of the tobacco are vertical rather than lateral it is possible to pack a paperboard hogshead with as much as 900 or 1G00 pounds of tobacco which corresponds favorably with quantities which are prized in wooden hogsheads of similar dimensions.

We have also found it desirable in connection with the prizing arrangement of FIGURE 13, to employ a corset which may be clamped about the hogshead prior to the introduction of tobacco. This corset is indicated at 56 and is designed to surround the hogshead between the upper and lower hoops-and-liners. Such corset 56 may be drawn snugly about the lrogshead 3@ by means of the clamps 56a with which it is provided, see also FIGURE 19. In this connection it will be noted that the corset itself has a hinged connection as generally indicated at Sob.

In order to prize a tobacco hogshead according to the arrangement so far shown a hogshead is placed on the support 53 beneath the shell Si) to which the hogshead 30 is clamped as indicated at 52, the shell itself being supported from the floor on the legs 51. The corset 56 is then placed about the hogshead 30 and clamped in position. The hogshead is then lled with tobacco and subjected to a pressing :operation by the charging or prizing means 55 whereafter additional tobacco is placed within the hogshead on top of that tlrst pressed and the prizing means again actuated. Usually two or three such prizing operations will serve to pack the necessary tobacco within the hogshead. After a suitable quantity of tobacco has been so placed within the hogshead the shell Se is released and removed whereafter the corset 56 is also released and removed. The head is then placed within the hogshead (in the same relative position as shown in FIGURE 11 in connection with the bottom head 4S) and the wires within the .top chime of the top hoop-andliner pulled tightly and twisted together so as to maintain such top in place.

In FIGURE 14 the charger mechanism 55a itself is provided with clamps 57 for engaging the upper edge of a paper hogshead 3G. The various charger mechanisms employed may be similar to that shown in the patents to H. G. Bell et al., 2,766,782; 2,734,450 and 2,712,407. In the arrangement of FIGURE 14 it will be understood that there is additional mechanism which reciprocates within the charger shell 55a and which serves to both introduce the tobacco into the hogshead 3d and thereafter compact same as desired.

The aforementioned steps in the prizing of a hogshead of this invention with tobacco are shown in FIG- URES 16, 17 and 18 wherein FIGURE 16 shows a tobacco hogshead 3o immediately after the prizing operation with the charger removed and the corset removed. FIGURE 17 illustrates the fact that the top is loose enough to permit the tobacco hogshead top 6I to be placed within the hogshead 39 on top of the prized tobacco. And in FIGURE 18 the hogshead is shown with the top 6I having been put in place, the wire 47 tightened and the additional Wires or straps d2 placed about intermediate portions of the hogshead in order to give it further support'. It is also possible that various of the arrangements taught in the said co-pending application for securing the mating edges of the hogshead body might be employed. As perhaps best seen in FIGURE 10, however, such additional support means for the mating edges of the hogshead might not be needed in the case of the paperboard hogshead of this invention wherein the upper and lower ends of the flap 35 are engaged within the notches 36.

Referring now to FIGURES 20-30 we therein illustrate that embodiment of our invention in which the paperboard hogshead takes the form of a four-sided box having also a top and bottom as will be described. Although we have shown this particular embodiment as being rectangular in cross-section it will be apparent to those skilled in the art that boxes having other shapes may be constructed if desired although we have found the four-sided box preferable for shipping and packing reasons. In general the boX type hogshead is formed of a paperboard blank suitably scored across its width to define the box sides rather than the individual staves as in the case of the barrel type hogshead. Also included are the metal hoops-and-liners which correspond closely to those of the hogshead rst described. Wire lacing is again employed although this is located a little diferently than in the case of the barrel type hogshead.

The basic parts of the box type hogshead are shown in FIGURES 20-24- wherein the blank is generally indicated at 79 and having a lseries of score lines 71 across its width. The blank is also scored longitudinally at two lines along each edge thereof so that the blank may be folded to provide the reinforcing folds 72 and 73 as perhaps best seen in FIGURE 23.

There is a hoop-and-liner for each longitudinal edge of the blank 7d, such hoops-and-iiners beingidentical with one another and corresponding generally to those indicated at 4t? in connection with the barrel-type hogshead earlier described. Because there are specific differences, however, the hoop-and-liner employed with the blank 7 ti will be described with application of new reference numerals. Thus We find that such a hoop-and-liner 74 comprises a substantially uninterrupted outer flat band 75, an outer edge protecting portion 76 bent at right angles to the band 75, a portion 77 slanting downwardly from the member 76, another portion 78 bent from the member 77 at substantially right angles towards the band 75, and another band 79 bent downwardly from the member 7S and parallel to the band 75, the distances between the bands 75 and 79 being just sucient nicely to receive the blank and its folds 72 and 7.3. As in the case of the hoop-and-liner it? the hoop-and-liner 74 is also made of metal.

There are a series of holes Si) which pass through the hoop-and-liner portions and 77, which holes align with holes 51 in the paperboard blank 7i) and its folds 72 and 73. A series of staples 82 maintain the blank 7i? and its foids 72 and 73 in proper position. Another series of staples maintains the hoop-and-liner '74 in proper position aiong the edges of the blank 7th, each such staple passing through the hoop-and-liner band portion 7S, the blank 79 and its folds 72 and 73, and the other hocp-and-liner 79, all as indicated at 83. The staples d3 are so positioned that the hogshead top or bottom 84-35 as the case may be will just tit between such staples and the hoop-and-liner portion 78 as will be readily apparent from an examination of FIGURE 30.

Each of the hoop-and-liners '74 is cut away in the region of the portions 77 as indicated at 74a so that the blank 7d, with the hoop-and-liners 74 aihxed thereto, may be bent `along the score lines 71 in order to bring it to the position generally indicated in FIGURE 24.

We have found it preferable to locate the score lines '71 of the blank 70 in such manner that when the-box type hogshead is assembled the juncture of the mating ends of the blank will be approximately in the middle of one of the side walls as clearly indicated in FIG- URES 20 and 24. In order to further strengthen the hogshead we provide the blank 70 with the tab 70a and the notches 70h. It will be apparent from FIGURE 24 that this arrangement permits the tab '70a to be received within the hoop-and-liner members which embrace the notches 7Gb.

The aligned holes 80 and 81 are for the purpose of receiving wire lacing 86 by means of which the box-type hogshead may be securely fastened about the wooden tops and bottoms 84, 85 employed therewith.

Referring now to FIGURES 25 through 30 we shall describe how a box type hogshead of the condition shown in FIGURE 24 is completed. A bottom 85 is placed on a support block S7. Wire lacing is placed through the holes 80, 81 in the manner shown in FIG- URE 25 so that the wire 86 lies adjacent the outer band 75 of the hoop-and-liner 74 through its greatest extent, such wire 86 passing through the holes 80, Si in the region of the corners of the box. A hogsnead comprised of the blank 70, hoops-and1iners '74 and wire 86 is wrapped about the bottom 85 while it rests on the support 87. The wire 86 is then drawn tight and its ends twisted together as indicated at 88. rthe box-type hogshead is then inverted to bring it to the position of FIGURE 27 wherein it is ready to be prized with tobacco. In this connection it will be understood that the various prizing and charging apparatus described earlier will be here employed with the exception that certain of the elements will be made rectangular in cross-section so as to accommodate the box-type hogshead as distinguished from the barreltype hogshead. The manner of prizing the tobacco within the box-type hogshead of FIGURE 27 is otherwise the same.

After the box-type hogshead has been prized with tobacco a top 84 is then put in place and the top wire 86 pulled and tightened as indicated at 88 to complete the arrangement as seen in FIGURES 28 and 30.

It is believed that this invention has been made clear by the detailed description herein above presented. A further description of this operation is not believed necessary.

It is to be understood that while this invention has been disclosed as embodied in certain particular structures and arrangements, these do not form a specific part of the invention except insofar as they are set forth in the subioined claims.

It will also be understood and apparent to those skilled in the art that modifications may be made without departing from its scope and spirit.
